Verfahren zur Darstellung von halogenhaltigen Küpenfarbstoffen.
Es ist bekannt, dass das in der Literatur unter dem Namen Indirubin beschriebene Kondensationsprodukt von Indoxyl mit Isatin von der Konstitution

EMI2.1
Lösung ein ; aus der Lösung geht die gebildete Farbstoffsulfosäure mit lebhafter Lilanuanco auf Wolle auf. In Alkohol und Benzol ist der neue Farbstoff auch in der Hitze 80 gut wie unlöslich. Anilin löst ihn in der Kälte kaum, in der Wärme ziemlich leicht mit rotvioletter Farbe ; Nitrobenzol löst ihn in der Hätte nur sehr schwer, in der Hitze jedoch leicht mit prachtvoll violettroter Farbe.
Beim Behandeln mit alkalischen Reduktionsmitteln wird eine hellgelbe Küpe erhalten, aus welcher Baumwolle in lebhaften violetten Tönen angefärbt wird, welche bei kurzem Seifen der Färbungen bei 900 in eine sehr lebhafte, durch vorzügliche Echtheitseigenschaften ausgezeichnete Heliotropnuancen übergehen.

EMI2.1
Solution one; The dye sulfonic acid formed goes out of the solution with lively Lilanuanco on wool. The new dye is practically insoluble in alcohol and benzene, even at high temperatures. Aniline hardly dissolves it in the cold, but rather easily in the warm with a red-violet color; Nitrobenzene dissolves it only with great difficulty in the had, but easily in the heat with a magnificent purple-red color.
When treating with alkaline reducing agents, a light yellow vat is obtained, from which cotton is dyed in lively violet tones, which, when the dyeings are briefly soaped, change into a very lively heliotrope nuance with excellent fastness properties.
